The San Francisco 49ers are bringing back a familiar face under center. According to the Athletic's Matt Barrows, the 49ers are signing quarterback Nate Sudfeld after Sudfeld threw in a wide receiver workout Monday.

The New York Jets and San Francisco 49ers are joining the Minnesota Vikings on the lookout for another wide receiver, according to The Athletic's Dianna Russini.

The 49ers wisely have some key veterans, most prominently Nick Bosa, Christian McCaffrey and Trent Williams, on schedules designed to keep them fresh and out of the fray from time to time. Quarterback Brock Purdy is a leader in a more reserved, analytical way. Deommodore Lenoir is stepping up to push the secondary.

There's no clarity yet on which quarterback will start for the San Francisco 49ers in their final preseason game.

Here's who stood out on Day 16 of 49ers training camp. Keep in mind, Mac Jones sprained his knee in the 49ers' preseason win over the Raiders on Saturday.

San Francisco 49ers cornerback Deommodore Lenoir hilariously explained how his friendship with Chase Lucas has evolved over the years.

Sudfeld is the fourth quarterback available for Saturday’s preseason finale against the Los Angeles Chargers, with Mac Jones and Carter Bradley still slinging it alongside Purdy. Sudfeld was brought in Monday to throw to three wide receivers who were auditioning as free agents.

Mac Jones won't be taking any quarterback reps for the 49ers in practice this week or in their preseason finale against the Chargers on Saturday. 49ers head coach Kyle Shanahan told reporters at a Tuesday press conference that Jones sprained his knee in last weekend's game against the Raiders.

The San Francisco 49ers were absolutely ravaged by injuries last season, which played a massive role in their disappointing 6-11. And once again this summer, the 49ers are once again experiencing medical issues.
